Cooling

   Some people believe in spirits or ghosts.  Some do not.  I have my own opinion but it's not the reason for this post.

   That reason would be how to duplicate the cooling effect that often gets attributed to ghosts.

   To do this you'll need a few things:

• 2 speakers (hopefully Bluetooth enabled)
• Android or iPhone cellphone
• An app for generating infrasound frequencies

   For the setup needed place both speakers together with enough space to fit your hand between (like you're about to handshake).  If they're Bluetooth speakers you can connect to them from the cellphone with any number of apps.  As long as the app can generate frequencies in the infrasound range it will work.

   Bring up the app you want, set the frequency it emits to around 7 Hz or 8  Hz and crank the volume.

   [NOTE: The frequency range around 7 Hz to 8 Hz is the resonant frequency for our internal organs.  You do NOT want to use speakers with too much power to do this.  It shouldn't be difficult to figure out the reason why.] 

   With the app running and the speakers going, place your hand between them.  There's 2 effects you might notice:

1. Cooling of the skin on your hand.
2. Weird feeling if your hand resonates (not everyone will notice this).

   That's all it takes.

   If anyone describes the effect as being caused by a ghost they have it backwards.

   It can be caused by infrasound generated from anything.

   Even from Cell Phones. 

The people I know with answers won't give them when asked.  So I have a few Questions.
